IMPROVEMENT IN CAR-AXLE LUBRICATORS.

Specification forming part of Letters Patent No. 127,391, dated May 28, 1872.

To all whom it may concern:

Be it known that We, RICHARD VosE and JAMES M. EVANS, ofthe city, county, and State of New York, have invented a new and useful Improvement in, Lubricating-Cushions for Railway Car-Axles, of which the following is a specification, reference being had to the accompanying drawing forming part thereof.

Figure l represents an external surface view of one of the cylindrical cushions, and a longitudinal sectional view of the other, the two constituting our invention. Fig. 2 is an end view of the same.

Our invention relates to a lubricating-cushion Jfor rai Way car-journals, formed of two hollow y inders composed of felt, cloth, or other equivalent porous substance, supported interiorly by metal springs, either rings or spirals. .Y

A A represent two -hollow cylinders or tubes, composed ofthick felt, cloth, or other suitable porous material, of suitable length and diameter to lit into the oil-box of a rail way car-journal. Within these felt-cylinders or tubes are tted and secured iu position several elastic metallic rings, B B B B, as seen in A, Fig. l, whereby the cylinders are made to retain their shape, and their upper surfaces are constantly pressed against the car-journal when in position in the oil-box, while at the same time the cylinders are rendered freely elastic and compressible, both longitudinally and diametrically, for convenience of inserting them into and removing `upward into contact with the journal, and the cylinders may be filled with waste wool or any elastic porous or fibrous substance to facilitate the conveyance of the oil to the journal. The

cylinders may be secured together, or they may be detached and placed side by side in the oil-box.

It is obvious that lubricating-cushions thus constructed are inexpensive, may be very readily and conveniently inserted into and removed from the oil-box, and must be thoroughly efficient in lubricating the journal.

What we claim as our invention, and desire to secure by Letters Patent, is-

A lubricating-cushion for railway car-journals, formed of the cylinders A A, composed of felt, cloth, or any other suitable porous substance, combined with metal springs placed within the cylinders, as and for the purpose specified.
